The Untapped Potential of Decentralized Solutions to Provide Safe, Sustainable Drinking Water at Large Scale
Dalberg Jan. 2017
This report argues that new approaches are needed to achieve the U.N. Sustainable Development Goal 6.1 by 2030. Through the analysis of 14 different small water enterprises, the report uncovers bottlenecks to scale and sustainability.
Sustainable Water Services Delivery Project Report
Fisher, M., Lecker, H., Samani, D., and Apoya, P.
Water and Sanitation for Africa, UNC Water Institute, Conrad N. Hilton Foundation
The results of this collaborative assessment show approximately 80% of the water points surveyed were functional - the functionality of older water points decreased by 2% per year of age and systems collecting a tariff were 40% more likely to be functional than those without a tariff.
Designing Philanthropy for Impact: Giving to the Biggest Gaps in India
Mangaleswaran, R., and Venkataraman, R.
McKinsey & Company
"Designing for impact" (before starting interventions) is integral to the dialogue in philanthropy in India. This paper assesses the biggest gaps in philanthropy in India along two dimensions - sectors or causes and modes or types of interventions. Water is identified as a critical gap.
Cluster-randomised controlled trials of individual and combined water, sanitation, hygiene and nutritional interventions in rural Bangladesh and Kenya: the WASH Benefits study design and rationale
Arnold et al.
The WASH Benefits study aims to fill the evidence gap on the effects of individual and combined interventions - water quality, sanitation, handwashing and nutritional - on diarrhea and growth when delivered to infants and young children. Here, study design and rationale are explained.
Effect of Household-Based Drinking Water Chlorination on Diarrhoea among Children under Five in Orissa, India: A Double-Blind Randomised Placebo-Controlled Trial
Boisson et al.
This study, designed to overcome shortcomings of previous double-blinded trials of household water treatment, provides no evidence that the intervention was protective against diarrhoea. Low compliance and modest reduction in water contamination may have contributed to the lack of effect.
Public Health and Social Benefits of at-house Water Supplies
Evans, B., Bartram, J., Hunter, P., Williams, A.R., Geere, J., Majuru, B., Bates, L., Fisher, M., Overbo, Al, Schmidt, W.
University of Leeds
At-home water supply has significant, measurable benefits compared to shared water supply outside the home provided that the service provided is reliable enough to ensure access to adequate quantities of water when required, suggesting a logical policy shift towards promotion of household access.
Setting Priorities for Development of Emerging Interventions Against Childhood Diarrhoea
Bhutta, Z., Zipursky, A., Wazny, K., Levine, M., Black, R., Bassani, D., Shantosham, M. Freedman, S., Grange, A., Kosek, M., Keenan, W., Petri, W., Campbell, H., Rudan, I.
Journal of Global Health
An expert panel exercise was conducted to assess feasibility and potential effectiveness of 10 emerging health interventions against childhood diarrhoea. Results show most collective optimism towards developing household or community-level water treatment.
Pooled Funding to Support Service Delivery: Lessons of Experience from Fragile and Conflict-Affected States
Commins, S., Davies, F., Gordon, A., Hodson, E., Hughes, and Lister, S.
Department for International Development
This review of 16 pooled funds highlights potential advantages - donor harmonization and operation on a larger scale with lower transaction costs, for example - but notes their performance frequently falls short of expectations, leading donors to pursue alternative or parallel channels of funding.
Inadequate WASH facilities contribute substantially to childhood mortality, and lead to health issues beyond gastro-intestinal such as respiratory infections and under nutrition. There are few detailed studies of scaled WASH programs so it is hard to conclude on best cost-effective delivery methods.
Market Assessment: Market-Based Provision of Water at the Community Level in Ghana
Safe Water Network
This market and feasibility assessment identifies the barriers and evaluates the potential for decentralized market-based approaches to provide sustainable safe water to the poor in rural, remote and small town communities in Ghana.
Impact of Water-Vending Kiosks and Hygiene Education on Household Drinking Water Quality in Rural Ghana
Opryszko, MC at al.
The American Journal of Tropical Medicine and Hygiene
The study indicates that households using for-profit water-vending WaterHealth Centers in Ghana had improved water quality compared with households using untreated surface water. However, only 38% of households using these kiosks by the third year, 60% of which had E. coli in their water.
